Application filed March 9,1901. Serial No. 50,475. (No model.) 7

To all whom it mag concern..-

Be it known that we, J MEs MOORE K. LET-- soN and FRANK WATTS BURPEE, citizens of the Dominion of Canada, residing at Van couver, inthe Province of British Columbia, Canada, have invented a new and useful Soldering-Machine, of which the following is a specification. 7

Our invention relates to improvements in soldering-machines in which we employ an endless chain passing over and beneath one side of a solder-trough and having thereon at intervals laterally-projecting fingers which pass over the rollway for the cans, such fingers being designed to roll the cans along; and the object of our invention is to generally improve the construction of machines of this class, to simplify the same, and primarily to provide devices on the conveying-chain that will prevent the cans from touching each other while passing through the solder-bath.

It is also our object to provide a machine that will solder cans of varied diameters and length and when desired such varied work to be done at the same time Without making any change or adjustment in the machine.

We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows afrontelevation of our machine. Fig. 2 is a plan of the same. Fig. 3 is a cross-section of the machine on'the line a a and viewed in the direction of the arrow in Fig. 1. Fig. 4 is a plan detail of the chain having the conveying-fingers thereon and its supporting-plate, and Fig. 5 is a sectional de tail of the machine through the acid-s11 pply on the line b b in Fig. 2.

Similar numerals and letters refer to similar parts throughout the several views.

In the construction of our machine a. indicates a solder-trough, which may be of the usual pattern, supported over the furnace b, and it indicates the rollway to where the acid 5 -is introduced to the ends of the cans preparatory to entering the solder. The furnace b may be and preferably is supported by a suitable support 01, so as to bring it the proper height with a minimum of expense and also to provide for the return-chain passing therebeneath, as is better understood in Fig. 3;

the floor by bolts passing through slotted apertures therein. D these pillars are right-angled brackets 11, having rectangular apertures therein, which Arranged to be fixed to loosely receive the pillars 10, and these brackets are fixed at the desired elevations on the said pillars by clamp-screws 12 passing through their front sides and engaging fiattened portions 10 on the said pillars. There are preferably four brackets 11, two on each pillar, and each pair of brackets 11 are disposed one near the top of the pillar and the other near the bottom of the pillar upon which they are mounted, and the upper and lower ones of the said two sets of brackets are disposed in' like horizontal planes, as clearly shown in Fig. 1.

Mounted in the projecting ends of the brackets 11 are spindles 13, which are all arranged in parallel alinement. On these spindles 13 are mounted sprocket-wheels 14, over which is passed an endless chain 15. This chain while passing over the solder-bath and acidsupply is supported by a plate 16, having raised parallel ribs 16, forming a channel for the chain 15. (See Fig. The inner side of the plate 16 lies over the solder-bath and slopes at a suitable angle toward the same, so that the lower rims of the rolling cans are always in contact with the hot solder.

Arranged at regular intervals along the chain 15 are fingers 17, which are fixed to special links and project at right angles .from

said chain over the plate 16, and owing to right-hand upper bracket 11, around which a belt g takes in the direction of the arrow. (See Figs. 1 and 2.) This keeps the upper side of the chain tight, and consequently holds the fingers in comparatively a rigid condition as they move along, and thereby the cans roll regularly, while they are prevented from touching each other by the intervening fingers. This last feature,as before intimated, is very important as,in the old style of machine, when the cans run together, the solder is smeared from one to the other, and frequently they become frozen (stuck) together by the cooling solder, which immediately causes serious trouble and delay by the chain slipping over same. The cans e are placed in a chute h at the left-hand end of the machine, which is on a sufficient incline to cause them to roll to where they are engaged by the fingers 7, at which point the sloping plate 16 is entered upon when said can is tilted, so that its lower edge is immersed in a bath of acid in the channel19, (see Fig. 5,) whence it is rolled onward and through the solder-bath and delivered arranged at opposite ends of a solder-bath, having an angled can rollway thcreover; right angled brackets having rectangular openings to receive said pillars, and means for fixing such brackets at the desired elevation; wheels mounted on the brackets, and a sprocketchain having laterally-projecting fingers thereon, taking therearound; a support-plate having a channel for the chain integral with the can-rollway, and means for imparting movement to the wheels carrying the chain.

2. A machine for the purposes described, comprising in combination, a furnace, a solder-bath, extending lengthwise and over the top thereof, pillars at each end of the furnace; upper and lower brackets vertically adjustable on the pillars, chain-wheels mounted on said brackets, an endless chain taking around the several chain-wheels, to pass under the furnace and over the top thereof, a can-rollway on the top of the furnace having an inclined portion extended over the solderbath, said chain having laterally-projecting fingers to engage the cans, all being arranged substantially as shown and for the purposes described.

In testimony whereof we have hereunto signed our names to this specification in the presence of two subscribing witnesses.
